The Easy-Inter Burial Container (Screw-in Coffin)

Donald Scruggs is a mechanical engineer and inventor. His most bizarre invention has come to be known as "the screw-in coffin." It's a casket shaped like a gigantic screw, with the idea being that it goes into the ground easier -- and uses cemetery space more efficiently by burying people (or pets) vertically. "It definitely is not for everybody," says Scruggs. Agreed. Here's a short video by PBS explaining the invention, and tastefully avoiding anything gruesome.

Also on Mental Floss:

DID YOU KNOW? Marlon Brando hated memorizing lines so much that he posted cue cards everywhere to help him get through scenes.
He even asked for lines to be written on an actress's posterior. (That request was denied.)
